Definitions

  • the invention relates to a hydraulically damped sleeve rubber spring according to the preamble of claim 1.
  • Such a sleeve rubber spring is known from JP-A-62-888834.
  • the pairs of chambers are assigned to one another in the axial direction and are each sealed in a liquid-tight manner.
  • a sleeve rubber spring is known from EP 0 0009 120, the damping effect of which is only available in a certain frequency range, which is unsatisfactory.
  • the invention has for its object to further develop a sleeve rubber spring of the type mentioned in such a way that it is easier to manufacture.
  • the pairs of chambers have a common, merging upper chamber.
  • such a design is of particular importance.
  • the chamber pairs can differ from one another by means of walls with a different bulging elasticity.
  • the bulging elasticity the total available bulging elasticity of the walls of each pair of chambers must be considered together, which makes it possible to provide a chamber within each pair of chambers that corresponds to a chamber of another pair of chambers with regard to the bulging elasticity of its wall.
  • the dimensions of the damping openings can be changed by varying the cross section and / or the length.
  • the assignment to a specific frequency of vibrations to be damped is often particularly easy to achieve.
  • the decisive factor in this regard is the frequency of vibrations introduced, at which the liquid mass contained in the damping opening starts to resonate due to the total bulging elasticities of the walls of the chambers adjoining on both sides.
  • the relevant conditions for the area of the two damping openings can also be designed differently from one another if the chamber pairs have a common upper chamber.
  • the sleeve rubber spring shown in Figures 1 and 2 consists of an outer tube 11 and an inner tube 12 which enclose each other and an inserted rubber body in a liquid-tight manner.
  • the rubber body contains two chamber pairs 1, 3 and 2, 4 lying one above the other in the damping direction, which have a common, merging upper chamber, the chamber pairs 1,3; 2.4 are separated from each other by elastic walls and filled with a hydraulic fluid.
  • the chambers 1, 3 and 2, 4 of each pair of chambers are connected by a channel-like damping opening 5 and 6, respectively, in a liquid-conducting manner.
  • the damping openings 5 and 6 have a matching cross section.
  • the end walls which delimit the chambers 1, 2, 3 and 4 in the axial direction have a bulging elasticity which differs from one another, the individual values being determined such that the bulging elasticity which can be measured overall in the region of each chamber pair 1, 3 and 2, 4 differs from one another designed.
  • FIG. 4 shows an embodiment in cross-sectional representation, in which the chambers 1, 3 and 2, 4, each forming a pair of chambers, are arranged laterally next to one another.
  • the sleeve rubber spring has a greater rigidity in the transverse direction than in the longitudinal direction. The rest of the design corresponds to that described above.
